Not sure what is going on but my x has decided to start locking/freezing up. It happens randomly when I open an app. Texting, emailing or some other random app. Its not totally locked up... If its charging the battery icon is still blinking or when it goes to"sleep" I can touch the screen and it will get bright again.

After thinking awhile.... It started when I had some issues updating 2 apps this weekend, 1 was a widget and the other a game. They updated but everytime I opened the market, they were still trying to download.

I messed around with it for a while and got them to download and install - again I guess.

I force stopped both apps, cleared the data from both and uninstalled. So far the phone seems much more responsive and no freezes.... Yet
